Underwater robot launched from Bermuda to cross Gulf Stream

29.03.2005


A small autonomous underwater vehicle, or AUV, named Spray was launched yesterday about 12 miles southeast of Bermuda. The two-meter-(6-foot)-long orange glider with a four-foot wingspan will slowly make its way northwest, crossing the Gulf Stream and reaching the continental shelf on the other side before turning around and heading back to Bermuda, where it will be recovered in July.



The voyage will be the vehicle’s second trip across the Gulf Stream.Spray made history last fall as the first AUV to cross the Gulf Stream, but this time it is making the trip from the other direction. The 112-pound vehicle was launched by researchers from the Woods Hole Oceanographic Institution near a long-term research site known as Station S. Scientists Breck Owens from Woods Hole Oceanographic Institution, and Russ Davis and Jeff Sherman of Scripps Institution of Oceanography at the University of California, San Diego, will track its progress and are able to communicate with the vehicle via satellite during the mission to change course or alter the information it is collecting while at sea.

The vehicle, which looks like a model airplane with no visible moving parts, will proceed north at about one-half knot, roughly half a mile an hour or 12 miles per day, measuring various properties of the ocean as it glides up to the surface and then glides back down to 1,000-meters depth (3,300 feet) three times a day. Every seven hours Spray spends about 15 minutes on the surface to relay its position and information about ocean conditions, such as temperature, salinity and pressure, via satellite back to Woods Hole, Mass., and San Diego.


Spray has a range of 6,000 kilometers, or about 3,500 miles, which means it could potentially cross the Atlantic Ocean and other ocean basins. Owens, Davis and Sherman plan to send the vehicle on its first round trip between Woods Hole and Bermuda later this year-- marking another first for an underwater vehicle.The successful trip last fall proved the viability of self-propelled gliders for long-distance scientific missions and has opened new possibilities for studies of the oceans. Research missions are being planned using the vehicle once field testing is completed.

Im Focus: A Challenging European Research Project to Develop New Tiny Microscopes

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.

To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...

Im Focus: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Im Focus: Tracing down linear ubiquitination

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.

Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
